Follicular Cyst

What is Follicular Cyst?

The follicular cyst is a type of functional ovarian cyst and occurs in the pre-menopausal phase. These cysts are fluid-filled sacs which develops in the ovaries. They are present during woman’s reproductive age and are rare in prepubescent girls and postmenopausal women are not at all affected.


  • If there is no ovulation or no LH surge, then the follicle grows and forms a cyst which eventually goes after 2-3 menstrual cycle but may persist.
  • If there is no fertilization, the corpus luteum, typically named atrophies turn into corpus albicans.
  • During the proliferation period of the menstrual cycle, the ovarian follicle matures and LH surge releases mature oocyte at mid-cycle, then the follicle transforms into a corpus luteum.


The follicular cyst usually occurs in women having a fertile and healthy menstrual cycle. Every month a woman develops a cyst-like follicle which produces the essential and functional hormone, progesterone and estrogen. If the follicle bursts out and releases an egg, then there is no issue, but if it does not break out, it can become a cyst and increase in size filled with blood or fluid.


Mostly, follicular cyst does not show any symptoms, but if the cyst ruptures or become more substantial, then the following signs may be seen:

  • Vomiting or nausea
  • Bloating or pressure in lower abdomen
  • Breast tenderness
  • Lower abdominal pain
  • Change in the duration of menstrual cycle

Severe, sudden and sharp pain in the lower abdomen needs medical treatment immediately and accurate diagnosis should be done as soon as possible.

Risk Factors

  • Usage of fertility drugs
  • Irregular menstrual cycle
  • Stress at high level
  • Early age of starting menstrual cycle
  • Excessive fat in the body especially in the torso region
  • Ovarian cyst in the past
  • Imbalance of hormone


Most follicular cysts disappear on their own and do not require any medical treatment. Doctors locate the cyst through physical examination or analyzing its symptoms. If a woman is in her reproducing years, then doctors allow the cyst to resolve itself and keep a regular check on the growth through vaginal sonogram or other tests.

If further symptoms are seen, then doctors go for pelvic examination to understand the reason for its occurrence. They may also recommend CT scan, MRI or other tests to get an accurate result because it often gets confused with appendicitis or other problems.


  • Although follicular cyst does not cause any issue, the cyst should be checked regularly if its growing or not.
  • If the cyst causes pain and irritation, then doctors may recommend removing surgically. Surgery may also be a suggestion if any type of cyst develops after menopause.
  • Doctors may prescribe contraceptives or other treatment methods to control hormone level and to prevent future development of a cyst.
